For the driving connection of, these four shafts in the mannershown in of the drawings, four casing heads are' providedto protect thegears and 2G I mayv rotate bodily together with its bevel gears holdthem in engagement. The outer sides of the blocks 25 which in ahorizontal plane, are rectangular in form, are provided with verticallyextending flanges 27 upon which the upper casing heads 28' are mounted.'Within the lower portion of each casing 28 are, located the beveledgears 29 carried by said vertical, telescopic shafts 30.

In the lower casings 28, the inner faces" of the same 'engage'theperipheral flanges '41 of the casing 42 which protects 'the shaftr83, as

shown in Fig. 5. From this description, it will be seen that each of thetelescopic shafts 3O 29 without interrupting movement of the boomlengthwise of'the machine. The shafts 30 are shown in'their closedrelation in Figs. 1, 3 and .5; 'while'theyare shown in'their extendedrelation in Fig. 2 while the boomis raised and I shifted forwardly. Theicasing 42 is divided into two tubes, two .cup members 43 being rivetedto the-casing sections and to each other. Within this intermediatecasing 43 a worm gear 45 is mounted on the shaft 38 for rotationtherewith, and a worm shaft "46 enters the casing and engages the gear45] for driving the excavating chains, and is itself driven from; themain powershaft 47 by gear 48. 'A very important feature of mycombined'ma chine is the provision of a conveyor just underneath theupper endof the excavating or digger unit,.and so mounted that it may be.swung about avertical axis by power means, material at differentpositions to deliver the desired.

7 It is characteristic of the conveyer mechanism disclosed in thisapplication that'such conveyer 68 may be swung outside the outline ofthe ma-'- chine, and in an'arc'extending over l8il degrees or somewhatmore, depending upon thecharac ter. of the surface of the ground wherethe conveyer may deposit such material. Such mounting of the conveyercomprises actuating means for the movement of the conveyer unit aboutits vertical and, further, power-driven means for actuating the conveyerbelt itself, and suchmounting will nowbe described.

Within a fixed casing '58, suitable to enclose a cylindrical hollowcasing 59, I enclose driving Worm gearing, and shown in vertical sectionin Fig. '6. The said verticalcasing 59 may rotate upon suitable bearings60, and has mounted thereon for its actuation a worm gear 61 engaged bythe driving worm 62 mounted on the horizontal drive shaft 63 whichprotrudes through the casing 58 .and is slidably and non-rotatably en'-gaged with the worm 62 by polygonal form of the shaft in cross-sectionor by keying, to prevent relative rotation of the shaft and worm.Integral with the casing :59 is anupper enlarged hollow gear casing64,preferably rectangularin outline in cross section but somewhat elongatedfin a direction lengthwise, of the belt.

Mounted on said casing 64 and rising "there-1:

from in-an upward andrearward di'rectionare provided frame arms 65jwhoseupperends are widely spaced and have bearings thereon66 for receivingtherein a horizontal drive shaft 67 members 71 are pivoted to the casing64 in suit-- able manner with the upper ends'thereof 'positioned justoutside of the frame 680:1 either side thereof, and adapted to engage,interchangeably,

' a bolt or pin on the members 68 to adjust the desired height of theconveyer on its pivot 67.

Suitable means may be provided for locking the brace members in. theiradjusted inclination.

The belt element 69 is driven from the roll '70 carried on the shaft 67,the latter having on-its ends outside the arms 65, suitablesprockets-.72.

A driving shaft 73 passesthrough the gear 'c'asing 64 parallellto'shaft67 and mounted upon the side walls 74 of casing 64 in bearings therein.Sprockets '72 similar to those on shaft 67 are mounted in alinement withtheir corresponding gears and sprocket chains 75 at either side engagethe respective sprockets.

By the structure above described, the rotation of shaft 63 may drive thecasings 59-and 64 together with their supported conveyer structure 68,about the axis of the vertical casing 59, while the. conveyer belt.69'may be actuated from shaft '73 while the conveyer is in any positionupon said axis. For driving the shaft 73, a vertical shaft 76 is'mountedwithin and longitudinally of the casing 59, being provided withsleevemembers 7'7 engaging the ends 78 interiorly of the casing 59, tomake proper rotation therein. Both ends of the shaft '76 are providedwith bevel gears '79, the upper one of which engages a bevel gear 80secured to the shaftf'ZB within the gear cas ing 64. A similar bevelgear80 is mounted upon a horizontal shaft 81 for engaging. ear 79 below thecasing 59, so that rotationof shaft-81j will drive theconveyer belt 69.-g

The sleeves'7'7 of the shaft '76 rotate upon suitable bearings 82 uponthe ends of the casing 59, so that the parts 59 and 76 are independentlyV rotatable, the latter driving the conveyer belt," while the formeradjusts the conveyer in its relative position about the axis of theshaft'76. The shaft 63 is elongated for quite an extent and is slidablymovable through the worm 62- whereby the shaft is immovable lengthwiseof the frame, but rotatable to drive the worm-, while the entireconveyer mechanism with its gearing and casings 58, 59 and 64,, aremovable longtiudinally of the machine as the-worm '62 slides along thefixed shaft 63, these arrangements of relative parts serving animportant function to be described now in further detail.

It should be noted, however, that the shaft 81 is carried lengthwiseo'fthe frame togetherwith the bevel gearSG, another portion of theshaft 81sliding through an element for driving thev same rotatably. I

While the casing 58 has been referred to as fixed, in describing ,theparts mounted within.

the same, suchterm' is intended to'be used in the sense of being fixedrelative to the rotating .parts, within. Because of a the arrangement ofthe boom and its chain digger mechanismltherej onfor movementlongitudinal of the machine, ithas been found necessary that the casing58,

together with allparts carriedpthereby; shall be =.-mounted forcorresponding longitudinal i movement in parallelism with thedirection Iof a movement in which .theboom travels, to insure vertical Ialinementof the, upper end of the chain digger mechanism for depositing theexcavated material, :and the approximate point above the axisofitheparts 59 and 76.; The structure for" causing such movement of theconveyermecha- ;nismwbodilyforward will nowxbe described." Mountedforwardfof the braces and the casingsf58, .59 and 64,; are frame braces5upon: which'the forward ends of the Ls 50 and plates" 5l; aremounted,=.the rear endsofsuch Us and 5;;plates being ,mounted securelyupon, the. long bracesilO, in, thetman'ner indicated i in Fig.

5 of the drawings. Between the rearwardposition of the plate orbar49which is shown in Fig. 5 of the drawings, andcarries the casing.

43 and drive" gearing forthe shafts 30, and the forward braces ,5, thecasing" 58 is mountedupon' said Ls50 and plates 51forreciprocatingimovee ment, thereon longitudinally of ;.the machine.

The-casing ,58 I is carried by vertical bars-s83 which maybe .L-bars.connected together by flat plates. 84* bolted'or. riveted thereto, thecas-. ing58 being ,directly mounted between saidplates '84 which.are'suitably spaced'to receive it,: as shown' ingFighiln i a v To. theupper ends of the bars 83. are secured outwardly-directed blockscorplates 85,

whereby the casing58 and its mounting may "readily travel lengthwise of'the. machine; Suitable inclined braces86 connect the bars83- andthewplates 84 for the .purpose .of. great rigidity.

The casing .58 is provided-at its :lower position withadownwardlyaextending. arm 87 perforated lua'to receive therein.thefshaft 81,' as shown in Fig-n1. To said'arm 87 thereis fixed a link88- extending1,.rearwardly .andconnected with actuating means for,reciprocatingthe conveyer in the-track just'described.

pivoted to a part190-of the base, and the upper 'end ,of bar '89 is thenpivoted toothe rear end of the actuating, link88; so thatswinging thelever-bar 89'on its pivot'will reciprocate ith'e 5,5xfcasing 58v alongthe parts 50 and 51, and as a result, when the digger mechanism'lf)moves toward or from the trench being dug, the long.

link 20 will move on its pivot'23,'. and the casing 585964, togetherwith the conveyer supfi i ported thereby, will be moved bodilylengthwise of the machine to cause the position of the conveyer toremain beneath the delivery end of the endless chain digger.

It is to be noted that the parts 20 and 89 are not connected directlytogether, though the former operates the latter; Instead, an inclinedlink or brace 91 connects the two, so that 1 the fulcrum of the bar 89may remain constant in position, while the digger boom is swinging thebar 89 and thence the casing 58. The movement of the latter, whichcarries with it the conveyer itself as well as its actuating mechanism,is guided positively by the horizontal travel of the blocks in thetracks resulting from the Us 50 and plates 51. j Thetravel is in theapron 69.

This latteractuation of the" conveyer apron 69 may be attained when theconveyerunit is adjusted toany one of its relative positions abouttheaxis of shaft76.

The connection of the boom 14 withthe conveyer unit 69 by the linksystem shown in Fig. 7 of the drawings, makes the mutual movement of thetWo elements very positive and certain,

so that the point upon the apron 69 directly' above the shaft '76 willremain substantially beneath the upper end of the digger unit 15 jdur-'ing the position of the lower end of the unit 15 in the trench. Sometime after the said lower end of the unit 15 has moved out of thetrench, a 'point willbe reached where the shaft 24 has moved forwardinthe machine faster than the vertical shaft 76 0f the conveyer mech:

anism has been advanced. by its connection with I position aslshown inFig. 2 is to provideia practical position which may be used, though notespecially over highways, one means for .moving thefboom;

.- downwardly andrearwardly to the operative pomounted longitudinallyof'said' main frame, one v the link 26, but it is now immaterial whatthe relative position of the two units 15 and 69 is, since the unit 15is no longer carrying material from the trench, and hence is notdelivering ,anything at points beneaththe shaft 24. When, .however, therear end of the digger unit 15 is again lowered as far as or below theground surface, the shaft 24 will have ,moved back to a position abovethe conveyer unit 69 as before. a The purpose of holding the boom inhorizontal transportation,

essential, for

sition, includes the winding reels 52 which. are

unwound when the unit 15 sinks downwardly. Thus the two units 15 and 69are actuated to-' gether from a common source of power, but they areadjusted together in proper relative posi% tion while it is essentialthat they should be, when; the unit 15 is of the structural form shownin these drawings.
